Related to bug 203341 - if an account is actually broken (e.g. I set the parameters wrong) and I set it to onlin,. the presence applet indicates it is online for ever, even if Mission Control failed to bring it online. The applet should indicate in some way if setting a presence failed.

I can't reproduce this. Given age of the bug, I imagine it's been fixed in the many rewrites.
